Report that shows all devices user has logged onto.

I am trying to create a report to find out what devices a user has logged onto. Can I get some help on this, please.

Have you looked at the built-in reports?

Information that you are looking for (computer name and user name) is stored in V_R_system .so it is straight forward to get the information using SQL query (given below)

select name0 from v_R_System where User_Name0 like 'eswar.koneti'

If you need to customize it , use the SQL views  https://gallery.technet.microsoft.com/SCCM-Configmgr-2012-R2-SQL-5fefdd3b and join the tables that you need info.

That query will only give you last logon user. plus there is already built in reports with those details, so no need to create another.
